How to check the broadcast receiver is running or not in android?

Question

Hai是否有可能检查广播接收器当前是否正在运行？如果可能，如何检查？

Answer 1

You can use dumpsys to help debug this for dynamically registered receivers:

adb shell dumpsys activity broadcasts

Use this in combination with grep and breakpoints in the debugger and you can find if your broadcast is registered at a certain time or not.

This is supposed to help with statically registered receivers, but I haven't used it myself:

adb shell dumpsys package

Answer 2

If you want to check it at runtime you can store a global boolean variable and set it to false and inside your onReceive() set it to true and before the onReceive() exit set it back to false . any time you can check this global variable to tell if that broadcast receiver is running or not .

if you mean you want to know if its work or not make a message to the log cat example

    onReceive(){
     Log.d("my broadcast","works");
    }

Answer 3

A BroadcastReceiver is not intended to be running in the background. It'll be woken up and killed in limited scope.
